Subject Re: Suggestions for upgrading cassandra

I'd review the CHANGES.txt to see what has changed and the NEWS.txt to see
what you need to do before upgrading (config changes, data storage changes,
etc).

Generally:

- Determine what version you are upgrading to, and why
- Snapshot the data across all nodes
- Upgrade the nodes one at a time (rolling upgrade)

For a change this major, you should set up a test cluster and see if there
are any changes after the upgrade.
